Sure, send me the sacral vids--especially if you searched far and wide for the best ones. That saves me some time.
As far as the questions a couple of the videos you sent say it's a good practice for the generators to have someone they trust (I'm imagining mainly a someone w/o an agenda) to ask you yes/no questions and that through that checking in and expression you'll begin to experience a clearer response? Anyway, that was my understanding.
Rereading your response, perhaps you are meaning you aren't sure what questions would be helpful though you understand the concept of asking questions?
